Description

DETAILED DESCRIPTION OF THE INVENTION (a) Field of Industrial Application The present invention relates to an automatic chemical analyzer, and particularly to an automatic chemical analyzer that can perform measurements at the same time as the analysis time starts.

The present invention also relates to an automatic chemical analyzer equipped with a spectrophotometer, and particularly to an automatic chemical analyzer for specimens such as blood, plasma, serum, urine, and other body fluids and secretions.

(b) Prior Art Analytical values of samples such as blood, plasma, serum, urine, and other body fluids and secretions are used, for example, in diagnosis and treatment guidelines. In order to analyze such specimens, a large number of specimens and analysis items must be analyzed in a short period of time (c). The worker turns on the power to start operation.However, at the time of opening, the heating tank and spectrophotometer in the reaction line have not reached the temperature that allows stable analysis, so it is difficult to perform accurate analysis. Therefore, until accurate analysis is possible,
The analyzer had to wait while the device was turned on, which was a complete waste of time for the analysis worker. In the spectrophotometer, there was a problem in that it took more than 20 minutes for the light source, amplifier, etc. to become stable and analysis possible. Moreover, despite such waiting times, it is impossible to avoid the need for sample analysis due to emergencies, etc., and sample analysis tends to be delayed.
A solution is desired.

An object of the present invention is to eliminate wasted waiting time at the start of analysis work in an automatic chemical analyzer having a spectrophotometer.

(d) When performing analysis using an automatic chemical analyzer that has a means to solve problems, the power can be turned on automatically at a predetermined time before the start of analysis work, and when the analysis work starts, The present invention provides an automatic chemical analyzer having a spectrophotometer that is ready for stable analysis.

That is, the present invention resides in an automatic chemical analyzer characterized by comprising a transformer and a time switch connected to the primary side of the transformer.

In the present invention, the automatic chemical analyzer refers to an automatic chemical analyzer equipped with a spectrophotometer in the photometry section, and the transformer here refers to a transformer connected to a power source.

In the present invention, the time switch is capable of closing a circuit at a scheduled time, and for example, conventionally used mechanical, motor, and electronic types are used. These time switches are installed in the circuit connecting the power source and the transformer.

Built-in timers can be used in automatic chemical analyzers. In this case, a switch provided between the power source and the transformer is connected to a built-in timer, and the timer controls the operation of the switch in a short period of time. However, even if the main power of the device is turned off, there is a timer that can store and display the time as well as set and store the scheduled connection time, and a switch that can automatically turn on the power of the automatic chemical analyzer based on the command from this timer. Preferably, the time switch has:

(e) Function The present invention is provided with a time switch connected to the primary side of the transformer of the automatic chemical analyzer. When the time has come, turn on the switch and
Automatic chemical analyzer can be turned on automatically. Therefore, by setting the time when the automatic chemical analyzer is turned on to be earlier than the analysis work start time by the warming-up time, the warming-up time is less likely to be brought into the analysis work time. (You can start analysis immediately.)

(F) EXAMPLES Hereinafter, embodiments of the present invention will be described with reference to the accompanying drawings, but the present invention is not limited in any way by these illustrative descriptions.

The figure is an explanatory diagram showing an outline of an embodiment of the automatic chemical analyzer of the present invention.

The automatic chemical analyzer 1 is connected to a power source 2 by a conductor 3, which is connected to a time switch 4. This time switch 4 includes a main switch 5, a timer 6, and a timer setting switch 7. therefore,
By having a built-in clock in the timer 6, this time switch 4 can memorize and display the time even when the main switch 5 is closed (OFF), and can also set and memorize the scheduled time to turn on the main switch 5. Is possible. This time switch 4 is connected to a transformer 8, which is connected to a light source 9, a photomultiplier tube 10. Amplifier 1
1. It is connected to a constant temperature bath 12, a recording section (not shown), etc.

The automatic chemical analyzer 1 of this example is configured as described above, so that, for example, the chemical analyzer fi
The time at which the main switch 4 of 1 is turned on is set in the timer 6. The timer 6 is set by inputting the date and time when the main switch 5 is turned on to the timer setting switch 7. The time to turn on the main switch 5 is, for example, approximately 30 minutes before the next day's analysis start time, and by setting the time to turn on the main switch 5 in this way, the timer 6 is automatically activated. , the main switch 5 can be turned on at a desired set time. Therefore, automatic chemical analyzer 1
Warming-up or initial settings are automatically performed, and the automatic chemical analyzer 1 is in a state where measurements can be performed stably at the start of analysis work. It can be performed. Therefore, for example, analysis and testing of specimens for emergencies and other cases can be carried out without delay.

The above explanation has focused on automatic chemical analyzers, but the same applies to spectrophotometers, in which the main switch is turned on automatically, allowing warm-up or accurate and highly accurate analysis. .

(G) Effects of the Invention In the present invention, a time switch is provided by connecting the primary side of the transformer of the automatic chemical analyzer, so the time at which the main switch of the automatic chemical analyzer is turned on is set and stored in the timer in advance. When the time reaches this point, the main switch is automatically turned on, and warming-up or initial settings are automatically started.

Therefore, according to the automatic chemical analyzer of the present invention, the time when the automatic chemical analyzer is turned on can be set to
In anticipation of the time required for warm-up or baseline correction in step 1II, the time can be set earlier than the analysis work start time by that time, so that the automatic chemical analyzer can stably perform measurements during analysis work. As soon as the analytical work starts, correct analytical values can be obtained, eliminating the disadvantage of waiting time seen in conventional automatic chemical analyzers, and improving the efficiency of the analytical work.

In the automatic chemical analyzer of the present invention, the time required for preheating the heating bath of the reaction line, warming up the spectrophotometer, or initializing the spectrophotometer is controlled by the action of a time switch connected to the primary side of the transformer. Therefore, the automatic chemical analyzer of the present invention can be turned on earlier than the analytical work start time by 1 minute. There is no need to wait for a while, and sample analysis or testing for emergency patients and other patients can be performed without delay, leading to the promotion of sample analysis or testing.
